Introduction

1.3 Summary of Features

1.3.1 Overview

The MX8400 MPEG Video/Audio/Data Multiplexer is housed in a 2RU, 19-inch rack

mounted unit. It is designed to meet the needs of IP distribution infrastructures. It is

ideally suited to a wide range of multiplexing and re-multiplexing applications. These

include primary multiplexing in headends for Direct-to-Home (DTH) satellite

contribution and distribution systems. It can also provide the hub for applications in

cable and terrestrial television central headends.

1.3.2 Main Features

• Up to eight independent output transport streams, each capable of creating a

multi-program stream conforming to the MPEG-2 transport layer specification

(ISO/IEC 13818-1 MPEG-2 Systems). Each multiplexer can be configured

independently e.g. output data rates, PCR mode of operation.

Note: The MX8400/BAS provides a single multiplexer engine which produces a

single output transport stream, additional multiplexers are a licensable

feature (MX8400/SWO/MUX).

• The maximum output bit rate for a single multiplexer is 250 Mbps. The

resolution, to which the output rate of a transport stream can be set, by entering

a bit rate, is 1 bps.

• The output bit rate can be set exactly to any of the DVB-T modes.

• SFN adapter functionality is included to produce an output transport stream in

accordance to TS 101 191 V1.4.1.

Note: When operating in SFN mode, the output bit rate is calculated as described

in Annex H.

• The maximum aggregated output bit rate is 1 Gbps, shared across the transport

streams created.

• Each multiplexer supports Ericsson Reflex Statistical Multiplexing (see also

Section 1.3.3 for Remote Reflex). This enables connected Encoders to be

grouped together to share an overall group bit rate, allocating a percentage of

the total bit rate to each Encoder depending on the complexity of the encoded

content.

• Ericsson Reflex Statistical Multiplexing allows bandwidth harvesting to help

maintain quality targets. Any bit rates not being used by multiplexed components

are distributed across all component video services. Data rate sharing between

components allows a user-defined higher quality-target component to take

bandwidth from user-defined lower quality-target components.

• Internal time references are used to ensure the multiplexing process does not

affect time critical data.

2/1553-FGC 101 1014 Uen B

1-6

Introduction

• Multiplexer output transport streams can be created from any services or

components carried on any input transport stream. A single component can also

be used in multiple output transport streams. Each multiplexer engine receives

PSI/SI/PSIP table data via nCompass Control and manages the carousel

insertion of that data into the associated transport stream output.

• A maximum of 8192 PIDs for each multiplexer is supported.

• The dynamic PID tracking of incoming services is supported.

• PID filtering is supported to allow the removal of unwanted PIDs.

• PID remapping is supported to allow a component received on one PID to be

output on a different PID.

• Missing incoming PIDs can be detected and used to initiate appropriate alarms

to nCompass Control. Detected PIDs can also be excluded from the monitoring.

• The MX8400 can operate in both active and redundant modes. Synchronization

of MX8400 configurations is automatically maintained for redundant mode of

operation.

• The MX8400 provides Program Level Redundancy by sourcing any transport

streams missing from the primary network from the secondary network without

affecting any other active service. Refer to Annex E, Redundancy Modes for

further details.

• The MX8400 supports dual redundant 10/100 Ethernet interfaces for system

control and for CA data.

• The MX8400 supports a single fixed power supply(100-240 V AC)

• The MX8400 supports an Alarm relay connection.

1.3.2.1 Program Specific Information Generator (PSIG)

PSIG (described by ETSI TS 103 197, DVB: High-end Implementation of DVB

Simulcrypt) is supported by this release of the MX8400.

The PSI Generator (PSIG) is defined as the head-end process(es) responsible for

generating MPEG-2 PSI (Program Specific Information) tables.

Note: Please refer to Annex I PSIG Support for further information.

1.3.2.2 Program Clock Reference (PCR)

• Multiplexing non-time stamped components (e.g. DVB Subtitles or MHEG Data)

between incoming services is supported.

• The MX8400 supports mixing time stamped components that reference valid

PCR PIDs from different remultiplexed feeds/incoming services. This is normally

only supported with feeds that use a single PCR reference in the incoming

transport stream or single PCR based Encoder's inputs.

2/1553-FGC 101 1014 Uen B

1-7

Introduction

• Each multiplexer supports the use of re-multiplexed PCRs (that is all multiplexed

services maintain their original program clock reference) or a single common

PCR (all incoming services are time adjusted to reference an internally

generated PCR).

Note: When operating in single PCR mode all contributing services must be

locked to a single common clock reference e.g. studio clock (HSYNC IN).

• Release 5 of the MX8400 provides the capability, under nCC control, to allow

the remultiplexing of transport streams without reading, analyzing or processing

the PCR. This means the user can specify that an incoming transport stream

uses a raw bit rate measurement (i.e. ignore the PCR values in the transport

stream).

1.3.2.3 Frequency Synchronization

• The main MX8400 system reference clock is an internal 27 MHz voltage

controlled oscillator. It can be locked to an externally sourced clock reference,

via the HYSNC input or GPS input. It can, also, be locked to the high-precision

on-board clock if no external source is available.

• Dual HSYNC clock inputs support the option of locking an internal frequency

reference to an external studio clock. The external clock reference is

configurable to accept 625 or 525 line video standards.

• Dual HYSNC clock output.

1.3.2.4 Table Generation

• The MX8400 can generate and insert the DVB Time and Date Table.

• The MX8400 can insert the DVB Time Offset Table. (This requires the use of

third-party equipment.)

• The MX8400 can insert the PSIP System Time Table. (This will require the use

of third-party equipment.)

1.3.2.5 TS IP Summary of Features

• Four independent

2

GbE transport stream data ports are provided. Each port

supports both RTP and UDP formatted packets.

• GbE interfaces support IP packet jitter removal

1.3.2.6 ASI Input/Output Summary of Features

• Four ASI outputs are provided. These support 188 and 204 byte transport

stream packets and are able to operate in byte and single packet burst mode.

• Two ASI inputs are provided. These support 188 and 204 byte transport stream

packets and are able to operate in byte and single packet burst mode.

2

Each port has its own MAC address.

2/1553-FGC 101 1014 Uen B

1-8

Introduction

• Indicators at the rear panel of the unit indicate the status of the ASI input and

outputs. These are described in Section 2.7.5 of Chapter 2, Installing and

Powering Up.

1.3.2.7 Dual PSU

The MX8400 Multiplexer is now available with dual hot-swap PSUs. See Chapter 5

for more information relating to the PSU.

Note: This is a new product and not an upgrade path.

1.3.3 Remote Reflex

1.3.3.1 Statistical Multiplexing

Statistical multiplexing delivers the efficient use of bandwidth whilst maintaining

picture quality. It makes use of the variable bit rate nature of video compression and

the improbability that all channels will peak in bit- rate demand simultaneously.

Grouping encoders together and allowing the group to share an aggregate pool of

bit rate enables the head-end system to provide either a better picture quality than

constant bit rate operation, or to maintain constant quality while adding more

channels into the multiplex.

Reflex is Ericsson's implementation of statistical multiplexing and is associated with

a multiplexer being co-sited with the encoder-sourced services. Remote Reflex is

used when services are sourced from encoders which are sited remotely from the

multiplexer.

1.3.3.2 Remote Statistical Multiplexing

With the introduction of IP-based connectivity between the MX8400 multiplexer and

the new encoder ranges, the Reflex technology has been extended to support

encoders located at remote locations over Wide Area Network to offer additional

benefits of further improved picture quality, higher efficiency and reduced capital

expenditure.

Up to 64 services for each output transport stream can be supported using Remote

Reflex. However, the total number of outgoing services across all transport streams

is limited to 400.

Remote Statistical Multiplexing is only available over IP and is not available for ASI

connections.

1.3.3.3 Reflex Operation

Remote Reflex allows statistical multiplexing of encoders located at a distance from

the MX8400, providing that the largest network latency between an encoder and the

MX8400 is no greater than 400 milliseconds.

Introduction

A system dependant delay constant is defined at the system configuration stage.

The MX8400 calculates the latency for individual Encoders and sets buffers

appropriately to ensure all Encoders within the system experience the same network

delay. This is achieved by ensuring the delay an Encoder service experiences is

equal to the predefined system delay constant.

An Encoder at a remote site will experience a larger delay in the network and is

therefore delayed less within the MX8400 input than an local based Encoder service

which is part of that the same Remote Reflex group.

Introduction

1.3.4 Conditional Access

1.3.4.1 DVB CA (Option)

• DVB CA, compliant with ETSI TS 103 197 V1.4.1, is supported via two RJ-45

GbE Ethernet connectors.

• CA is supported on all eight output transport streams.

1.3.4.2 BISS

• BISS

3

Modes 0 and 1 are supported as standard on this release. The

scrambling mechanism, as defined in the DVB-CSA specification, is applied at

the Transport level only. This is configured using nCompass Control.

- Mode 0: No scrambling.

- Mode 1: All components are scrambled by a fixed Control Word (CW),

derived from a clear Session Word (SW). The MX8400 accepts the session

word is via an XML control interface. Any invalid session words will be

rejected (it must be a 12 character hex string).

• Individual transport streams can be scrambled simultaneously with either

DVB CA or BISS but not individual components. The MX8400 will only support

one scrambling method on a single PID.

1.3.5 Single Frequency Networks Functionality

The MX8400 Multiplexer supports up to eight output transport streams with SFN

data. The SFN data for each output transport stream can be configured

independently via nCompass Control.

Note: Please refer to Annex H Setting up the SFN Functionality for further

information.

1.3.6 Extended Functionality

Multiplexer functionality can be extended by the use of purchasable options. See

Chapter 3, Hardware Options and Software Licenses for information.
